Watch Mesmerizing Blue Lava Erupt From This Hawaiian Volcano

A video captured the phenomenon of blue lava tumbling out of the Kilauea volcano in Hawaii on Wednesday.

The effect, sometimes referred to as the "blue hour," occurs as the sun sets, causing light to refract off the glowing lava and creating this optical illusion of blue lava, the Telegraph reported.

Kilauea is one of the most active volcanoes on the Big Island of Hawaii, and it attracts tourists from around the world. Some adventurous visitors even hike the 7.4 miles round-trip through the national park where Kilauea is located just to catch a glimpse of the erupting volcano.
